Definitions

  • the present invention relates to a coloring high-molecular particulate material and coating composition including the same.
  • the object of the invention is to provide a coloring high-molecular particulate material and a coating composition including the same, enabling a coating film to be produced having colorfully designed appearance of various sprinkled patterns of textiles and suede, a texture with smoothness and roughness at the same time as well as visual appreciation of tint configuration to wall papers, synthetic resin sheets or the like.
  • coating compositions have their colors by mixing coloring pigments of each color into a varnish.
  • the coloring pigments used for such coating compositions have particles up to 10 ⁇ m in particle diameter to obviate color shading, to enhance dispersion properties and to provide a uniform color tone.
  • coating compositions become more desirable as the diameter of the particles which make them up become smaller. For example, when a red compound and a white compound are blended to prepare a sprinkled pattern, tiny dots of coloring pigment of different colors are aligned on the film surface of the coating composition and are thoroughly mixed with each other to form a plain color with no spattered pattern, i.e., it visually appears to be a pink coating film, and is hence poor in decorative properties.
  • the present inventors have conducted extensive research in an attempt to prepare a coating composition having excellent decorative properties which can serve to provide colorful designs and have found the following.
  • Color particles having a particle diameter of about 10 - 200 ⁇ m were prepared, and these were mixed with differently colored particles into an aqueous varnish to prepare a coating composition in which the color particles are aligned on the coating surface to provide a visually colorful design like that seen in textiles or suede.
  • resin particles have first to be prepared which can act as nuclei for a pigment which enables the color particles to be dispersed in a varnish to prepare a coating composition.
  • the present inventors attempted to obtain the color particles by pearl polymerization by introducing a monomer and coloring pigments into water.
  • the polymerization was inhibited by the coloring pigments or only the monomer was polymerized posing difficulties for polymerization with coating the coloring pigments.
  • the present inventors attempted emulsion polymerization by blending a monomer, an emulsifier and coloring pigments into water; interfacial polymerization by polymerizing at the interface between an oil phase and a water phase and offset separation by mixing a poor solvent into a good solvent having coloring pigments and a polymer dissolved therein or like polymerization.
  • the coating film was cured with fluid solvent remaining in the coloring particles which resulted in coloring of the interior and particles having poor resistance to scratches, etc.
  • an emulsion resin coating composition mixture including a coloring pigment is admixed with polymer particles having a diameter of from 10 to 100 ⁇ m in the presence of an anionic activate surface agent to disperse and stabilise the coloring pigment.
  • a metal salt is then introduced to obtain coloring high-molecular particulate material having a color membrane.
  • This coating composition has excellent decorative properties, and has tiny dots of its coloring pigments aligned on the coating surface to provide the same colorful effect as that found on textiles or suede as well as the fastness properties of a coating film with non-uniform color shading thereon.
  • Such a method of preparing a coating composition is much improved over the conventional methods. However, it has the drawback of not completely coating the particle surface of the synthetic emulsion resin with the coloring pigments.
  • the afore-mentioned problems can be solved by the presented coloring high-molecular particulate material characterized in that a mixture of dispersed and stabilized coloring pigments and an emulsion resin are admixed with particles of a vinyl chloride synthetic resin containing a plasticizer in an amount of about 4.7-50 wt.%, wherein a metal salt is introduced to obtain coloring high-molecular particulate material having an average particle diameter of about 10 to about 200 ⁇ m.
  • a mixture of dispersed and stabilized coloring pigments and an emulsion resin are admixed with particles of a vinyl chloride synthetic resin containing a plasticizer in an amount of about 4.7-50 wt.%, wherein a metal salt is introduced to obtain coloring high-molecular particulate material of 10 to 200 ⁇ m in particle diameter.
  • the emulsion resin to be favorably used in the present invention can be any of those whose stability is weakened or destroyed in the presence of metal ions, and which then agglomerates or adheres like a gel to the particle surface of the vinyl chloride synthetic resin containing the plasticizer described later.
  • emulsion resins examples include acryl, styrene acryl, polyester, polyurethane, vinyl chloride-vinyl acetate copolymer, vinyl chloride-acryl copolymer or like synthetic resins and mastic, acaroid, benzoyl, dragon's blood, elemi, sandrach or like natural resins.
  • the surfactants to be used in the invention are not specifically limited, it is preferable to use positive ionics, negative ionics, nonionics or ampholytic surfactants.
  • the preferred amount of such surfactants to be added so that the emulsion may be destabilized in the presence of metal ions is up to about 1 wt.% based on the loadings of the emulsion resin having particles not larger than about 0.1 ⁇ m in particle diameter although the amount is not specifically limited.
  • Antiforming agents, film forming assistants or the like may optionally be introduced into the emulsion resin when required.
  • preferable coloring pigments are ones conventionally known such as titanium dioxide, amber, red iron oxide, chrome yellow, iron blue, carbon black, ultramarine blue, manganese violet or like inorganic pigments and Hansa yellow, benzidine yellow, toluidine red, phthalocyanine blue, phthalocyanine green, dioxazine violet or like organic pigments.
  • extender pigments such as barytes, calcium carbonate, clay, talc, etc. can be used in combination with the above coloring pigments.
  • the amount of the coloring pigments to be favourably used is not particularly limited. However, about 2-300 parts by weight per 100 parts by weight of said emulsion resin solids is preferred.
  • Usable vinyl chloride synthetic resins are not specifically limited but ones formed by suspension or emulsion polymerization are preferred such as a vinyl chloride homopolymer, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl chloride copolymer, ethylene-vinyl acetate-vinyl chloride copolymer, urethane-vinyl chloride copolymer, chlorinated vinyl chloride copolymer or the like.
  • the vinyl chloride synthetic resin prefferably be selected so that a coloring high-molecular particulate material can be obtained having an average particle diameter of about 10-200 ⁇ m slightly variable depending on the loading of the plasticizer though, and more preferably about 10-170 ⁇ m.

  • the amount of the plasticizers to be added is about 4.7-50 wt.%, more preferably about 23-44 wt.%, based on the weight of vinyl chloride synthetic resin after the addition of the plasticizer.
  • the vinyl chloride synthetic resins prepared by suspension polymerization are suitably used in an amount of about 33 to about 44 wt.%, and the resins prepared by said emulsion polymerization are suitably used in an amount of about 23 to about 38 wt.%.
  • the plasticizer is contained in an amount of less than about 4.7 wt.%, then the coating efficiency of the emulsion resin containing coloring pigments to the particle surface of the vinyl chloride synthetic resin is too low. On the other hand if the plasticizer is contained in an amount exceeding about 50 wt.%, then the coating film has insufficient strength resulting in the particles of the resin being softened, and a reduction in the tack strength among the particles which leads to difficulties when removing individual particles at the final stage.
  • the typical method of admixing the vinyl chloride synthetic resin and the plasticizer is to use a HENCEL MIXER agitator, during which stabilizing or modifying agents for the resin may be introduced when required.
  • the desirable amount of the emulsion resins to be used is about 0.05-2.0, more preferably about 0.1-1, when the amount of the vinyl chloride synthetic resin including the plasticizer used is 1 (part by weight). If the emulsion resin is present in an amount of less than about 0.05, then there is insufficient to coat thoroughly the particles of the vinyl chloride synthetic resin which results in the particles having low tinting. On the other hand, if the emulsion resin is present in an amount exceeding 2.0, then its particles tend to agglomerate like a gel which results in the particle strength being deteriorated.
  • a large amount of the vinyl chloride synthetic resin provides lower fluidity. In this case water may be added for good fluidity when required.

  • the most suitable amount of the metal salt to be added may be conveniently determined by finding outthe amount of metal salt, which when blended with the emulsion resin, causes it to become agglomerated like a gel.
  • water can be added to the metal salt forming an aqueous solution of the metal salt, and the emulsion resin then admixed therewith.
  • the weight ratio of the aqueous solution of the emulsion containing coloring pigments and the metal salt is about 7:3 to about 3:7, more preferably about 6:4 to about 5:5, taking particle stability into consideration, although it is not particularly limited.
